Answer:
21, 24, 29
Step-by-step explanation:
To calculate the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
a₁ = 1² + 20 = 1 + 20 = 21
a₂ = 2² + 20 = 4 + 20 = 24
a₃ = 3² + 20 = 9 + 20 = 29
Answer:
Position of point X on the number line must be X = -27
Step-by-step explanation:
Notice that there are 14 units between W and Y, since the absolute value of their difference is :
| -15-(-29) | = | -15 + 29 | = 14
Now let's write an equation that tells as what is the distance between W and X in terms of WY knowing that we want WX to be 1/7 of WY:
This is telling us that the point X must be located two (2) units to the right of point W. That is W + 2 = -29 + 2 = -27
Position of point X on the number line must be X = -27
Answer:
(x) = -3 + x
Step-by-step explanation:
n = last test
(87 + 78 + 61 + n) : 4 = 78,5
87 + 78 + 61 + n = 78,5 x 4
n = 314 - 226
n = 88
It is 50 because you have to subtract the area of the triangle (14) from the area of the square (64)
